+Subject: [PATCH] Gentoo: override paths for system-wide install based on
+ sys.prefix
+
+Override all default distutils install paths to ones suitable for
+system-wide install when sys.prefix indicates we're running the Gentoo
+system-wide install of PyPy with no prefix overrides (e.g. virtualenv).
